In the next weeks, I will show you some games that can be installed and played on your Raspberry Pi without an emulator. This games are often available from your packet manager, so it is very easy to install them. Many games are Open Source versions of classic games which are now playable on ARM processors too.

Raspberry Pi games

A really good site that I found is here. Someone did the job to evaluate games that are available from the packet manager and started to check if they are playable on Raspberry Pi. Some of them are yet tested and work without problems, others are too heavy for the Pi. I will get you some highlights of this list and I will show you the best playable games for your Raspberry Pi. Stay tuned!

Your Raspberry Pi is perfect for controlling and monitoring data. A really good topic is monitoring of your network and all network traffic. For this, there are many different Open Source programs, but you can say that there is a standard program called Nagios. Nagios can do things like:

• observe protocols (HTTP, SMTP, POP3, FTP, SSH,…)
• control host resources (processor usage, memory usage, …)

Everything will be logged, so you may analyze this data offline. With this tool you can easily control your IT architecture.

Installation

Installation is very simple. Nagios is a very common program, so it is part of the package manager of many Linux distributions. So you can easily install the Nagios from your preferred packet manager:

Nagios is controlled from a web interface. For this it is important, that there is already a web server running on your system. If not, you can find a tutorial on how to do this here.

Today I have a really funny thing! An Open Source First Person Shooter for all Counter Strike Fans. I will show you how to install and configure an Assault Cube Server on your Raspberry Pi. Assault Cube? Yes, this is an Open Source Counter Strike that is really funny to play and it works on your Raspberry Pi. It runs very smoothly and fast, so it is possible to host a multiplayer game for a LAN party on Raspberry Pi (or use it in your local network for example school or so…)

On GitHub you can find many interesting projects. There are also many things related to the Raspberry Pi. Raspcontrol is a control center that runs on your web server and informs you about the status of your Pi!

Installation

For the installation of this web interface, you will need a running web server. I show you how to do this for your Pi in one of my older articles. The installation of raspcontrol is quite simple, but first we need a package called git:

We will install raspcontrol directly into our www directory, so we do not have to configure anything. So we change the current directory: Continue Reading…

If you are using a computer, you should always think about security! Linux systems are quite secure instead of Windows System, which are more in danger about viruses. Security is a topic that you should consider, because no system is 100 percent save. Systems with a always up internet connection (file server, mail server, web server, …) are in danger of attacks. For this it is a good idea to build a de militarized zone, which is between your internal network and the router to the internet. There you will connect your servers and you should install 1 or 2 firewalls to allow or deny certain connections.

Planning

For your Raspberry Pi this means the following. We want to reduce traffic, so that only port 80 and 442 communicate. If your Raspberry Pi is used as web server that can reached from outside over HTTP and HTTPS. If you need to connect through SSH to your Pi from outside, we also have to give permissions to port 22. A better idea would be to change the SSH port to something you only know (for example 22356 or so).
